      “Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience.” Ex. 1005 ¶ 17; Pet. 16. Patent Owner does not challenge this definition or present its own. Accordingly, we credit the testimony of Dr. Ratner regarding the level of ordinary skill in the art, and find that a person of ordinary skill in the art would have had an undergraduate degree in Computer Science or a related field, such as Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience. This level of ordinary skill is reflected not only by the information presented by the parties, but also by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 9

      “We agree with and adopt Petitioner’s reasoning and determine Rabinovich to be a printed publication. We credit the unrebutted testimony of Dr. Rabinovich regarding the consistency of his professional practice in 1998 for republication of his AT&T technical memoranda on a webpage that he managed on AT&T’s publicly accessible website. Furthermore, we find the December 1998 IEEE article corroborates the public availability of Rabinovich on that website, and would have been a roadmap, for one of ordinary skill in the art of data management and optimized access to data, to be guided to Rabinovich. See Reply 19–22. As Petitioner points out, Patent Owner’s own declarant states that Rabinovich and the December 1988 IEEE article “are ‘similar[]’ in that they both address ‘problems in network connectivity caused by multiple clients accessing servers.’ (Ex. 2006 at 12).” Id. at 21. Additionally, the passage in the December 1998 IEEE article that cites to Rabinovich refers to an algorithm in Rabinovich for optimizing access to data in order to increase performance. Id. Accordingly, we find that footnote 16 of the IEEE article, which contains the URL to Rabinovich, would have guided one of ordinary skill directly to Rabinovich. We are, therefore, persuaded, that Rabinovich is a printed publication under 35 U.S.C. § 102.” slip op. at 12

      “object xs. Rabinovich defines cnt(s,xs) as the “total access count for xs,” which is equal to cnt(xs). Ex. 1006, 11. According to Dr. Ratner, “[t]he metric cnt(s,xs) measures the total number of times in that window that replica xs has been served to a client computer.” Ex. 1005 ¶ 253. As Patent Owner points out, Rabinovich teaches replicating object xs if the ratio of cnt(s,xs) over aff(xs) is greater than m, i.e., a non-zero value. PO Resp. 34; Ex. 1006, 12, Fig. 4. In view of this, we agree with Patent Owner that if cnt(s,xs) has a value of zero, meaning that object x has not been served to any client computer, then the ratio of cnt(s,xs) to aff(xs) will be zero, i.e., less than m, and Rabinovich will not carry out its replication step. This means that Rabinovich will not replicate object xs until xs has been accessed by a client computer at least once, such that the access count for xs is greater than zero. In this regard, we agree with Patent Owner that Rabinovich object xs is not “sen[t], from the at least one data storage device to the another data storage device . . . independently of an access of the at least one client computer” because Rabinovich teaches explicitly that object xs is not sent unless there has been at least one access from the client computer. We are not persuaded by Petitioner’s argument that Rabinovich” slip op. at 18

      “pieces” Claim 1 recites “each file including a plurality of individual pieces, the pieces containing parts of the files.” Ex. 1002, 25:67–26:1. The other independent claims recite limitations commensurate in scope. Neither party proposes explicitly a construction of the term “piece.” Petitioner argues that “files are inherently composed of pieces in the form of bits that make up bytes, the bytes themselves being pieces of the file.” Pet. 32. Patent Owner argues that construing “piece” to cover “bits and bytes” of a file “would read out the ‘pieces’ limitation from the claim entirely” (PO Resp. at 29–30) and that “one of ordinary skill in the art would not read the ‘pieces’ limitation of the claim to include bits and bytes” (id. at 30). The claims themselves define “piece” by requiring that a “file” have a “plurality of individual pieces,” but do not establish a lower bound—i.e., a minimum number of bits or bytes—to qualify as a “piece.” Patent Owner identifies no support in the ’680 patent for its contention that “piece” or “pieces” excludes a byte or bytes of a file, relying instead solely on the testimony of Dr. Paul S. Jacobs. Id. (citing Ex. 2006 ¶¶ 38, 39). We are not persuaded by Dr. Jacobs’s conclusory testimony. Because “piece” and “pieces” are limited by the claims only to being a subset of a file and because a byte or collection of bytes of a file is a subset of that file, we are persuaded that the broadest reasonable interpretation of “piece” and “pieces” in light of the Specification of the ’680 patent encompasses a byte or bytes. slip op. at 7

      “We are unpersuaded by Patent Owner’s position. First, the claim language does not recite any physical or structural connection, rather, only “electrically coupling.” Pet. Reply 3, 8–9. In addition, the specification of the ’150 patent does not define explicitly the term “selectively electrically coupling.” Therefore, as in IPR2014-00882 and IPR2014-01011, we refer to its ordinary and customary meaning, as would be understood by one of ordinary skill in the art in the context of the entire disclosure. Translogic Tech., 504 F.3d at 1257. A technical dictionary, the IEEE Dictionary,4 defines “electrical coupling” as “[e]lectrical charges in conductors of a disturbed circuit formed by electrical induction.” Ex. 3001. The IEEE Dictionary explains that “[s]ince the ratio of a conductor’s electrostatic charge to the potential difference between conductors (required to maintain that charge) is the general definition of capacitance, electrical coupling is also called capacitive coupling.” Id.

      “Based on our review of the ’150 patent and the types of problems and solutions described in the ’150 patent and cited prior art, we conclude a person of ordinary skill in the art at the time of the ’150 patent would have a Bachelor’s degree in electrical engineering, computer engineering, computer science, or related field, and at least one year of work experience, including familiarity with computer memory systems and related industry standards such as JEDEC standards for DRAM memories and memory modules. We further note that the applied prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). D.

      “To testify as an expert under Federal Rule of Evidence 702, a person need not be a person of ordinary skill in the art, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008); see SEB S.A. v. Montgomery Ward & Co., 594 F.3d 1360, 1372–73 (Fed. Cir. 2010) (upholding a district court’s ruling to allow an expert to provide testimony at trial because the expert “had sufficient relevant technical expertise” and the expert’s “knowledge, skill, experience, training [and] education . . . [wa]s likely to assist the trier of fact to understand the evidence”); Mytee Prods., Inc. v. Harris Research, Inc., 439 F. App’x 882, 886–87 (Fed. Cir. 2011) (non-precedential) (upholding admission of the testimony of an expert who “had experience relevant to the field of the invention,” despite admission that he was not a person of ordinary skill in the art). As noted above, Dr. Jagannathan has designed and implemented hardware virtual memory caches, and researched theoretical performance measures of various cache coherency protocols, and has experience in the design of memory systems. We find that, although Dr. Jagannathan may be less experienced than Dr. Sechen in the area of memory module design, he is nonetheless qualified sufficiently to testify about memory systems and memory modules.

    • ExcludeMotion to exclude, deniedDenied

      “We have reviewed the parties’ contentions on this issue, and exercise our discretion to determine that Petitioner’s Reply and the Jagannathan Supplemental Declaration will not be excluded. We find that, although they may be “inartfully” drafted, the first Jagannathan declaration and Petition sufficiently outlined Petitioner’s position on the function of the chip select signal, namely, that the chip select signal was not itself the logic signal enabling operation of bit-switches. We further find that Petitioner’s Reply and the Supplemental Jagannathan Declaration did not present an entirely new rationale of unpatentability based on Takeda, JEDEC, and Connolly. Cf. Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369–70 (Fed. Cir. 2016) (affirming Board’s exclusion of reply brief and declaration that changed unpatentability theory to “an entirely new rationale”). Moreover, there is no dispute that Patent Owner was aware of Petitioner’s position by no later than the Jagannathan deposition, which preceded Patent Owner’s Response by ten days. Patent Owner could have addressed Petitioner’s chip select signal contention, procedurally or substantively, in its Response, but chose to raise the issue only after Petitioner filed its Reply and Supplemental Jagannathan Declaration. Accordingly, Patent Owner had notice of Petitioner’s position and an opportunity to refute that position in its Response.” slip op. at 24

      “The difference in the opinions of the two experts is that Dr. Sechen believes a person of ordinary skill in the art would have an additional four years of experience, education, or a combination of the two, beyond that proposed by Dr. Alpert. See Ex. 1009 ¶ 7. According to Dr. Alpert, the difference in the proposed levels of ordinary skill in the art is not material to any dispute over claim construction or patentability in this inter partes review. Id. We accord greater weight to Dr. Alpert’s opinion as to the level of ordinary skill in the art because he has experience in both teaching students and working with engineers in the industry, while Dr. Sechen’s experience is primarily in teaching. Compare Ex. 1007 ¶¶ 7, 21 with Ex. 2012 ¶¶ 3, 5. Moreover, based on our review of the ’434 patent and the types of problems and solutions described in the ’434 patent and cited prior art, we agree with Dr. Alpert’s opinion on the level of ordinary skill. Accordingly, we find that a person of ordinary skill in the art at the time of the ’434 patent would have a Bachelor’s degree in electrical engineering, computer engineering, or in a related field and at least one year of work experience relating to memory systems, and would be familiar with the design of memory devices, memory modules, and BIST.” slip op. at 10

      “The above disclosure uses the term “operable independently” to describe the data handlers as being discrete and functioning without being physically or logically connected to each other. Based on our review of the ’434 patent, the specification and claim 27 both use the term “operable independently” in the same manner, i.e., to describe a feature of the data handler that is distinct from its data generation feature. We agree with Petitioner, therefore, that when interpreted in the context of the ’434 patent in its entirety, the claim term “operable independently” “merely means that each data handler can operate without influence or control by any of the other data handlers.” Reply 5. The ’434 patent specification uses the term “operable independently” in accordance with its plain and ordinary meaning, and we find no basis for applying the narrower construction advanced by Patent Owner to any of the challenged claims. Accordingly, we interpret “operable independently” as “operable without influence or control by another.” See Cuozzo, 793 F.3d at 1278–79.” slip op. at 19

      “Based on the above description in Averbuj, we agree with Patent Owner that Averbuj describes memory interfaces (the alleged data handlers) that are configured to produce address and control signals, and that Averbuj describes producing address and control signals in certain circumstances, e.g., when Averbuj’s sequencer (the alleged control module) specifies writing data in a particular pattern that requires transformation to conform to a particular configuration of a memory module. See PO Resp. 33. We also agree with Petitioner, however, that Averbuj’s memory interfaces are further configured to apply to the memory modules the same address and control signals received from, and produced by, the sequencers for testing (see Reply 15), e.g., when the sequencer sends signals that can be applied, without modification or transformation (see Ex. 1003 ¶ 56), directly to a memory module irrespective of its physical configuration. Thus, Petitioner has shown, by a preponderance of the evidence, that Averbuj’s sequencer meets the limitation of “a control module configured to generate address and control signals for testing the memory devices” as recited in challenged independent claims 1, 20, and 29 of the ’434 patent.” slip op. at 41

      “As discussed in Section IV.B.2.e., a petition must include “[a] full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing law, rules, and precedent” (37 C.F.R. § 42.22(a)(2)), and “[a] reply may only respond to arguments raised in the corresponding . . . patent owner response” (37 C.F.R. § 42.23(b)). We agree with Patent Owner that the Reply does more than merely respond to or rebut arguments made in Patent Owner’s Response; rather, it sets forth a theory that was not presented clearly in the Petition. Patent Owner’s position is supported by the fact that Dr. Sechen, whose skill level is at least (and appears to exceed) that of the ordinary artisan, apparently was unable to envision how Huang and Averbuj could be combined. Further, Dr. Alpert’s second declaration includes, at a minimum, opinions as to the understanding of the ordinary artisan with respect to the teachings of Huang and Averbuj that were not presented in his first declaration. In our judgment, consideration by the Board of the above-noted arguments in the Reply and evidence presented in Dr. Alpert’s second declaration in support thereof would be improper under 37 CFR § 42.23 and unfair to Patent Owner. We have, however, reviewed and considered the arguments in the Petition and evidence therein, and are in agreement with Patent Owner that Petitioner has not provided adequate explanation or evidence to support its contention that one of ordinary skill in the art would have had a reasonable expectation of success in combining Huang and Averbuj. Accordingly, Petitioner has not met its burden to show, by a preponderance of the evidence, that claims 7–12, 17, 18, 20–25, 27, 28, and 30–35 would have been unpatentable over Huang and Averbuj.” slip op. at 59
